John Baldwin 2ee8325f42 A better fix for handling different FPU initial control words for different ... ABIs: - Store the FPU initial control word in the pcb for each thread. - When first using the FPU, load the initial control word after restoring the clean state if it is not the standard control word. - Provide a correct control word for Linux/i386 binaries under FreeBSD/amd64. - Adjust the control word returned for fpugetregs()/npxgetregs() when a thread hasn't used the FPU yet to reflect the real initial control word for the current ABI. - The Linux/i386 ABI for FreeBSD/i386 now properly sets the right control word instead of trashing whatever the current state of the FPU is.
